DETAILED DESCRIPTION

Water mismanagement is one of the leading causes of poverty, economic crises, population displacement, illness, and malnourishment in the world. This is especially true in the developing world, where access to water is often limited, expensive, and/or inconsistent. In many cases, water collection and retention can consume inordinate man-hours and financial resources. Water access is often limited in the developed world as well, particularly in regions of low or inconsistent rainfall.

Water leakage can take a heavy toll on economies and infrastructure. For example, over 20% of potable water in the UK is lost to leaks before it reaches homes and business. The costs of making repairs to such leaks are often prohibitive, as locating the leaks can pose significant challenges. Such leakage can also exacerbate droughts and other water shortages. The consequences of such leakage and waste are made more dire as the frequency of droughts and rainfall shortages increases.

Given the importance of water to everyone's everyday lives, it is often desirable to optimize the performance (e.g., water usage, water distribution, water saving) of water systems. Such water systems can include irrigation systems, water utilities, municipal water distribution, and other water systems. One way to further optimize water systems is to utilize water usage meters that provide live and reliable flow data.

FIG. 1 schematically illustrates an embodiment of a water usage meter 1. The usage meter 1 can include a housing 2. As illustrated, the housing 2 can include a water flow path 3 extending therethrough. The water flow path 3 can include an inlet 3 a and an outlet 3 b. The cross-sectional width and shape of the water flow path 3 can vary or remain unchanged over all or a portion of the length of the flow path 3 between the inlet 3 a and outlet 3 b. For example, the water flow path 3 can include one or more areas of decreasing width (e.g., nozzle regions) or increasing width (diffuser regions) between the inlet 3 a and outlet 3 b.

In some embodiments, the housing 2 includes a dry compartment 4. The dry compartment 4 can be fluidly isolated from the water flow path 3. The dry compartment 4 can house one or more components of the water usage meter 1. Fluid isolation of the dry compartment 4 from the water flow path 3 can reduce the likelihood of damage to the components of the meter 1 from water or other fluids present in the flow path 3.

The water usage meter 1 can include a power generator 5. The power generator 5 can be positioned at least partially within the dry compartment 4 and at least partially within the water flow path 3. One or more seals (e.g., O-rings, sealing sleeves, grommets, etc.) can be connected to the power generator 5 and/or housing 2 to reduce the likelihood of water ingress into the dry compartment 4 from the water flow path 3. The power generator 5 can be configured to produce power via interaction with the water or other liquid flowing through the flow path 3. The power generated by the power generator 5 can be provided to the other components of the water usage meter 1, thereby reducing or eliminating the need for external power connections. In some embodiments, the water usage meter 1 includes a battery 6. The battery 6 can be configured to receive power from the power generator 5 can store that power for use by other components in the water usage meter 1. As illustrated, the battery 6 can be positioned at least partially within the housing 2. In some embodiments, the battery 6 is positioned at least partially outside of the housing 2 and/or within a second housing (not shown). The power generator 5 can be configured to provide power directly to the battery 6 and/or to other components of the water usage meter 1.

In some embodiments, the water usage meter 1 includes a water flow sensor configured to measure the rate of water flow through the water flow path 3. For example, the water usage meter 1 can include one or more of a turbine, Pitot tube, venture tube or other flow-measuring device. In some embodiments, the power generator 5 is configured operate as a water flow sensor. For example, the power generator 5 can be a turbine configured to rotate in response to fluid flow through the water flow path 3. The turbine can produce a voltage useful for providing power and/or for conversion to a velocity measurement, as described in more detail below.

One or more additional sensors 7 can be operably connected to the water usage meter 1. The sensors 7 can be wholly or partially within or without the dry compartment 4. In some embodiments, the water usage meter 1 includes a first sensor 7 a and a second sensor 7 b. The sensors 7 can be used to measure parameters (e.g., temperature, pressure, velocity, viscosity, purity, clarity, etc.) of the fluid within the water flow path 3, environmental factors (e.g., humidity, light, temperature, etc.) of the environment surrounding the water usage meter 1, and/or other parameters. In some embodiments, one or more of the sensors 7 is in fluid communication with the water flow path 3. One or more seals can be used in connection with such sensors to reduce the likelihood of water ingress into the dry compartment 4 or into the environment surrounding the housing 2 from water flow path 3.

The water flow sensor (e.g., the power generator 5) and/or other sensor 7 can be operably connected to a signal generator 8. The signal generator 8 can be positioned at least partially within the dry compartment 4. In some embodiments, the signal generator 8 is positioned at least partially outside of the dry compartment 4 and/or housing 2. The signal generator 8 can be configured to relay information from the sensors 5, 7 to an external device or network. The signal generator 8 can be powered by the battery 6 and/or directly by the power generator 5.

FIGS. 2-7 illustrate an embodiment of a water usage monitor 10. The water usage monitor 10 can include a housing 12. The housing 12 of the water usage monitor 10 can include one or more fluid inlets 14. As illustrated, the housing 12 can include one or more fluid outlets 18. In some embodiments, the fluid outlet(s) 18 are in-line with the fluid inlet(s) 14 and positioned on an end of the housing 12 opposite the fluid inlet(s) 14. In some embodiments, the fluid outlet(s) 18 are not in-line with the fluid inlet(s) 14 and are positioned on an end of the housing 12 opposite the fluid inlet(s) 14 or on a side of the housing 12 lateral to the fluid inlet(s) 14. In some embodiments, as illustrated, the housing 12 includes a single fluid inlet 14 in-line with a single fluid outlet 18.

The fluid inlet 14 can be configured to fluidly connect to a water source or some other fluid source. For example, the fluid inlet 14 can connect to a pipe, hose, spout, faucet, or other fluid source. In some embodiments, the fluid outlet 18 is configured to fluidly connect to a water line or fluid line. For example, the fluid outlet 18 can be configured to connect to a pipe, faucet, hose, or other fluid line. In some applications, the water usage monitor 10 is used as an end-of-line device to be attached to a water outlet such as a faucet or spout. In some such configurations, the fluid outlet 18 can be configured to output water or other fluids to an end user (e.g., directly into a sink or at the end of a hose). In some applications, the water usage monitor 10 is used in-line in a water system.

The housing 12 can include a first housing portion 22 (e.g., a wet housing) and a second housing portion 26 (e.g., a dry housing). The first and second housings 22, 26 can be configured to connect to each other via use of one or more fasteners 27, detent fittings, clips, threaded engagements, friction fittings, or other releasable attachment structures or methods. In some embodiments, the first and second housings 22, 26 are connected to each using adhesives, welding, or other permanent or semi-permanent attachment structures or methods. The first and second housing portions 22, 26 can be configured to connect to each other in a fluid-tight manner such that water and other fluids are not permitted to escape an interior of the housing 12 between the first and second portions 22, 26 of the housing 12.

As illustrated in FIGS. 6-7, the monitor 10 can include one or more sockets or plugs 15 a, 15 b. The sockets/plugs 15 a, 15 b can be configured to facilitate wired communication between two or more components. For example, multiple monitors 10 can be connected to each other using USB, RJ45, and/or other connections. In some applications, one or more monitors 10 are configured to connect to a network hub 100 via a wired connection. In some applications, all connections between the monitors 10 and network hub(s) 100 are wireless.

As illustrated in FIG. 8, the housing 12 can have an interior chamber 30. The interior chamber 30 can span one or both of the first and second housing portions 22, 26. One or more water usage meter components can be positioned at least partially within the interior chamber 30 of the housing 12. For example, a power generator assembly 34 can be positioned at least partially within the interior chamber 30. In some embodiments, the water usage meter 10 includes a sensor 38 (e.g., a pressure sensor, temperature sensor, optical sensor, ultrasonic sensor, or other sensor). The sensor 38 can be positioned at least partially within the interior chamber 30. In some embodiments, the sensor 38 is configured to operate at pressures of greater than or equal to 0.5 psi and/or less than or equal to 60 psi.

Moving to FIG. 9, the housing 12 can include a fluid flow passage 40 extending between the fluid inlet 14 and the fluid outlet 18. Preferably, the fluid flow passage 40 is fluidly isolated from the internal chamber 30 of the housing 12. The fluid flow passage 40 can have either a constant or variable cross-sectional area between the fluid inlet 14 and the fluid outlet 18. As illustrated, the fluid flow passage 40 can include a narrowed portion 42 (e.g., a control portion) having a reduced cross-sectional area with respect to the portions of the fluid flow passage 40 upstream and/or downstream of the narrowed portion 42. In some embodiments, the fluid flow passage 40 is substantially straight. Utilization of a straight or substantially straight fluid flow passage 40 can reduce undesired pressure buildup in the fluid flow passage 40. In some embodiments, using a straight or substantially straight fluid flow passage 40 can reduce turbulence in the fluid flow passage 40.

As illustrated, a sensing portion 46 of the sensor 38 can be in fluid communication with the fluid flow passage 40. For example, the first housing portion 22 can include one or more bores 47 (FIG. 9) extending between the internal chamber 30 of the housing 12 and the fluid flow path 40. The sensing portion 46 of the sensor 38 can extend through the bore. In some embodiments, the sensing portion 46 of the sensor 38 can be configured to measure pressure, temperature, or other fluid features. One or more seals (e.g., O-rings, sleeves, grommets, or other sealing structures) can inhibit or prevent fluid ingress from the fluid flow passage 40 into the internal chamber 30 by way of the bore 47. As illustrated, the bore 47 can be oriented at an angle oblique to vertical (e.g., up and down in the frame of reference of FIG. 9). In some embodiments, the bore 47 is oriented at an angle oblique to the axis of rotation of the turbine 50, as described below. Orienting the bore 47 at such angles can reduce the overall height (e.g., vertical dimension in FIG. 9) of the housing 12 required to fit the sensor 38 within the internal chamber 30 of the housing 12.

As illustrated in FIGS. 10 and 11, the power generator assembly 34 can include a turbine 50. The turbine 50 can include a plurality of turbine blades 54 extending radially outward from a turbine hub 58. The turbine 50 can be configured to operate as a Pelton turbine and to rotate in response to water flow or other fluid flow through the fluid flow path 40. At a given point of rotation of the turbine hub 58, at least one turbine blade 54 can be positioned in the fluid flow path 40. In some embodiments, between 10-30%, between 5-25%, between 15-45%, and/or between 20-35% of the turbine blades 54 are positioned in the fluid flow path 40 at a given point of rotation of the turbine hub 52. In some embodiments, approximately 25-28% of the turbine blades 54 are positioned in the fluid flow path 40 at a given point of rotation of the turbine hub 52.

In some embodiments, the first housing portion 22 and/or second housing portion 26 include a turbine cavity 59 in which the turbine 50 is at least partially positioned. The turbine cavity 59 can be in fluid communication with the fluid flow path 40. In some embodiments, the turbine cavity 59 has a diameter greater than a diameter of the turbine 50, including the turbine blades 54. The diameter of the turbine cavity 59 can be less than 5% greater than the diameter of the turbine 50. In some embodiments, the diameter of the turbine cavity 59 is less than 10%, less than 8%, less than 4%, less than 2%, and/or less than 1% greater than the diameter of the turbine 50. Sizing the turbine cavity 59 to be very close to the same diameter of the turbine 50 reduces dead space in the turbine cavity 59. In some embodiments, such relative sizing can reduce drag between the turbine blades 54 and fluid within the turbine cavity 59 as the turbine hub 58 rotates. The overall diameter of the turbine 50 can be between 0.25 and 1.5 inches, between 0.75 and 4 inches, between 1 and 3 inches, and/or between 2 and 10 inches. Many variations in the diameter of the turbine 50 both greater and smaller than these disclosed diameters may be used. In some configurations, utilizing a reduced cross-sectional area 42 of the flow path 40 in the vicinity of the turbine blades 54 can increase pressure and velocity of the fluid that impacts the turbine blades 54. This increased pressure and/or velocity can reduce the volumetric fluid flow rate required to rotate the turbine 50. In some embodiments, narrowing the fluid flow path 40 upstream and into the turbine 54 can facilitate reliable a predictable direction of flow onto the turbine blades 54. The increased performance of the turbine 50 can facilitate generations of high voltages for powering the components of the water usage monitor 10. For example, the turbine 50/power generator assembly 34 can be configured to generate at least 12 volts of electricity at flow rates as low as 4 liters per minute.

In some embodiments, it can be advantageous to expand the cross-sectional area of the fluid flow path 40 downstream of the control passage 42. Such an expansion 41 can facilitate use of a fluid outlet 18 having a cross-sectional area the same as or substantially the same as the cross-sectional area of the fluid inlet 14. Maintaining uniform inlet and outlet cross-sectional areas for the fluid flow path 40 can reduce the impact of the water monitor 10 on the overall flow rate of water into and out from the monitor 10. In some embodiments, the fluid inlet 14 and fluid outlet 18 do not have the same cross-sectional area. In some such cases, the water monitor 10 can be configured to perform with little or no impact on the overall flow rate of water or other fluids into and out from the monitor 10. Providing an expansion 41 of the cross-sectional area of the flow path 40 immediately downstream of the turbine 50 can reduce the likelihood of backpressure effects associated with such an expansion. For example, the turbine blades 54 can generate turbulence in the water downstream of the control passage 42 and break up pressure blockages which may otherwise propagate in the area of the expansion 41. In some embodiments, the turbine blades 54 can reduce or eliminate any back flow into the control passage 42. In some configurations, proximity of the turbine blades 54 to the expansion 41 can reduce the likelihood of settlement of debris or other sediment in the vicinity of the expansion 41, as the turbine blades 54 can stir up the sediment and increase the likelihood that the sediment is carried through the outlet 18 of the housing 12.

As illustrated in FIG. 10A, the expansion 41 of the can include an expansion wall 43 extending from the control passage 42. In some embodiments, the expansion wall 43 is frustoconical, hemispherical, flat, or some combination thereof. The expansion wall 43 can expand away the centerline CL of the fluid flow path 40 at an expansion angle. The expansion angle can be at least 10°, at least 20°, at least 30°, at least 45°, and/or at least 60°. In some embodiments, the expansion angle is approximately 63°.

As illustrated, the expansion wall 43 can emanate from the control passage 42 at an uppermost point on the turbine 50 with respect to the frame of reference of FIG. 10A. In some embodiments, a line drawn perpendicular to the centerline CL of the fluid flow path 40 and passing through the upstream end of the expansion wall bisects the turbine 50. In some such embodiments, the drawn line passes through the axis of rotation of the turbine 50. Positioning the beginning of the expansion 41 at the uppermost point of the turbine 50 can allow the blades 54 of the turbine 50 to impart downstream energy into the water in the expansion 41 to reduce the likelihood of pressure buildup in and/or back flow from the expansion 41 to the control passage 42.

As illustrated in FIG. 11, the power generator assembly 34 can include a fixed portion 62 connected to the turbine 50. The fixed portion 62 can be connected to the first housing 22 via one or more fasteners 63, adhesives, welding, and/or other connection structures or methods. In some embodiments, the fasteners 63 are arranged about the perimeter of the fixed portion 62. The fasteners 63 (e.g., and corresponding fastener holes) of the fixed portion 62 in a such that the fasteners 63 pass through an entire thickness of the first housing 22 without interfering with the fluid flow path 40, turbine 50, turbine blades 54, or other components of the monitor 10. The fixed portion 62 can have a width greater than the diameter of the turbine cavity 59. The turbine 50 (e.g., the turbine hub 58) can be configured to rotate with respect to the fixed portion 62 of the power generator assembly 34. One or more seals (e.g., O-rings) can be positioned between the fixed portion 62 and the portions of the housing 12 (e.g., the first housing portion 22) surrounding the turbine cavity 59. These seals can be configured to inhibit or prevent fluid ingress into the internal chamber 30 of the housing 12 from the turbine chamber 59 and/or from the fluid flow path 40. In some embodiments, these seals can be configured to flex or otherwise deform in the event of a pressure spike in the fluid flow path 40. The seals can be configured to rotationally flex (e.g., about the axis of rotation of the turbine 50) in response to pressure spikes in the fluid flow path 40. Flexing or deformation of the seals can reduce the risk of damage to the turbine in the event of a pressure spike.

The turbine 50 can include a plurality of fixed magnets 64. The fixed magnets 64 can be positioned in a circumferential array about an axis of rotation of the turbine 50. Conductive wiring 70 can be wrapped around the fixed magnets 64. The turbine 50 can include one or more rotating magnets 66. The one or more rotating magnets 66 can be positioned radially outward from the fixed magnets 64. The rotating magnet(s) 66 are preferably configured to rotate as the turbine 50 rotates in response to fluid flow through the fluid flow path 40. Rotation of the rotating magnet(s) 66 with respect to the fixed magnets 64 causes the rotating magnet(s) to pass through the magnet fields of the fixed magnets 64, thereby generating an electric current (e.g., an AC or DC current) through the conductive wiring 70 (e.g., wire coils). In some configurations, the turbine 50 can include several wire coils. For example, the turbine 50 can include at least 3, at least 5, at least 7, and/or at least 10 coils. In some embodiments, the turbine 50 includes 9 coils. This electric current is passed through the wiring 70 to a circuit board 74, which is configured to convert the electric current to usable power. For example, the circuit board 74 can include a rectifier circuit or other structure to convert AC current or DC current from the power generator 34 into DC current (or a modified DC current) for various components of the water usage meter 10. The circuit board 74 can be streamlined to include only those components necessary to convert power and receive signals from the components in the water usage monitor 10. For example, the circuit board 74 can be designed not to include components necessary for data storage. The usable power can be transmitted to other components of the water usage monitor 10. For example, one or more wires 76 can connected the power generator assembly 34 to a battery, to the sensor 38, and/or to other components of the water usage monitor 10. The frequency and/or amplitude of the current generated by the turbine 50 can be used to calculate flow rate of water or other liquids through the water usage monitor 10. For example, increased frequency of the voltage signal can correlate to increased velocity. Comparing the velocity measurement to the known physical dimensions of the flow path 40 can facilitate precise calculation of the absolute volumetric flow rate of water or other fluids through the monitor 10. In some embodiments, the monitor 10 (or the cloud 102 or the hub 100, described below) is configured to calculate pressure in the fluid flow passage 40 from the flow rate measurements obtained by the turbine 50.

FIG. 11A schematically illustrates an example of the components used to calculate velocity of flow through the fluid flow path 40. As illustrated, the power generator 34 can include the turbine 50. The turbine 50 can be connected to a voltage generator 37. For example, the turbine 50 can be connected to the voltage generator 37 via a shaft 35. In some embodiments, the voltage generator 37 can be positioned at least partially within the turbine hub 58, as described above with respect to FIG. 11.

The voltage V generated by the voltage generator 37 can be directed to a rectifier circuit 39. In some cases, the voltage V output by the voltage generator 37 is a direct current. The direct current can be a pulsating or oscillating direct current. For example, the direct current generated by the voltage generator 37 can oscillate up to values of 20V, 30V, 40V or more. The rectifier circuit 39 can be configured to receive the direct current from the voltage generator 37 and convert it to a lower and/or non-pulsating current (e.g., 5V direct current, 3V direct current, or some other value). The rectifier circuit 39 can be positioned in the interior chamber 30 and/or on the circuit board 74. The rectifier circuit 39 can convert the voltage V to direct current and/or transmit usable power to a transceiver 53 and/or antenna 55 and other electrical components of the monitor 10. In some embodiments, the rectifier circuit 39 transmits usable power to one or more sensors 38 of the monitor 10.

In some embodiments, the rectifier circuit 39 directs usable power to a battery 57. The battery 57 can be used to power the one or more additional sensors 38, transceiver 53, microprocessor 49, and/or antenna 55. In some configurations, the battery 57 is used to power components of the monitor 10 when the turbine 50 is not generating power. The voltage V of the voltage generator 37 can be transmitted to a frequency counter 43 either in series with or in parallel with the rectifier circuit 39. The frequency counter 43 can be configured to output a signal indicating the frequency and/or amplitude of the voltage V generated by the voltage generator 37. As such, the same voltage V can be used to both power the electrical components of the monitor 10 and provide the raw data for calculating fluid flow rate through the fluid flow path 40. Calculating fluid flow rate directly from the frequency and/or amplitude of the generated voltage V can reduce the need for additional sensors. The frequency counter 43, transceiver 53, and antenna 55 can positioned on the circuit board 74 and/or at least partially within the interior chamber 30. One or more of the components of the circuit board 74 and/or within the interior chamber 30 can be operably connected to a microprocessor 49. In some embodiments, the microprocessor 49 is configured to perform the function of the frequency counter 43. The microprocessor 49 can be positioned on the circuit board 74 and/or within the interior chamber 30. The transceiver 53 and/or antenna 55 can be configured to communicate with a network hub 100 or network of distributed servers 102. In some applications, more than one monitor 10 is configured to communicate with a single hub 100. In some applications, each hub 100 is configured to communicate with a single monitor 10.

As is also shown in FIG. 11A, the system may also include a controllable component 250 that can be controlled by the microprocessor 49. The controllable component 250 may comprise a sensor that can be configured or enabled to detect particular parameters about the fluid flowing through the monitor or it may be a controllable valve that can be used to alter fluid flow in the system in the manner that will be described in greater detail in connection with FIG. 17 below.

Referencing FIG. 11B, the water usage monitor 10 can include an alignment feature configured to stabilize and/or align the turbine 50. For example, the turbine cavity 59 can include a protrusion or recess 77 configured to engage with a recess or protrusion on the turbine 50 (e.g., on the turbine hub 58). The alignment feature can reduce wobble, tilting, or other rotational instability of the turbine 50 as it rotates.

As illustrated in FIG. 12, a plurality of water usage monitors 10 can be connected to a cloud network 102 or other network of distributed servers to form a monitoring network 90. For example, each of the water usage monitors 10 can include a signal generator configured to generate and send signals (e.g., wireless signals) to the cloud 102. This can be accomplished via a Wi-Fi, Bluetooth®, RF transmission, LoRaWAN, Radio/cellular, GSM, or other wireless signal. In some embodiments, two or more of the monitors 10 can communicate with each other, either wirelessly or via a wired connection. The monitors 10 and/or network hub(s) 100 can form a mesh network in which communications are sent between the monitors 10 and network hub(s) 100.

Preferably, the one or more network hubs 100 communicate the signals from the water usage monitors 10 to the cloud network 102. In some embodiments, all data processing is performed on the cloud network 102 (e.g., the network of distributed servers), without processing on the hub(s) 100 or at the individual monitors 10. This arrangement can be advantageous for a number of reasons. For example, the design and structure of the monitors 10 can be simplified due to the lack of a need for data processing. This simplification can reduce the size and/or power consumption of the monitors 10. In some cases, retaining all data processing on the cloud network 102 can reduce the risk of security compromise if a thief or other bad actor were to obtain an individual monitor 10 or network hub 100.

The communication between the network hub(s) 100, cloud 102, and individual water usage monitors 10 can be bi-directional. For example, as explained above, the individual water usage monitors 10 can relay information to the network hub(s) 100 which can, in turn, relay information to the cloud network 102. The system can be configured such that the cloud 102 and/or hub 100 can relay information back to the water usage monitors 10 to tune, calibrate, or otherwise affect a change in operation of the water usage monitors 10. Remotely controlling the software on the monitor 10 can facilitate generations of new and/or different data for analyzing large and small scale water usage characteristics of a given application. Utilizing such functionality with or without mesh network functionality can create scalable network architecture.

As illustrated in FIG. 13, the water usage monitors 10 can be used in a water or fluid network 110 comprising a plurality of pipes 112, 114. For example, the water usage monitors 10 can be positioned in a plurality of generations of piping. As illustrated, at least one water usage monitor 10 can be positioned in line with both first generation pipes 112 (e.g., pipes connected to a water hub or water source) and second generations pipes 114 (e.g., pipes downstream of the water usage monitors 10 connected to the first generations pipes 112). The water usage monitors 10 can be provided with unique identifiers (e.g., QR codes, bar codes, RF tags, alphanumerical codes, etc.) that can be entered/scanned by an installer to identify the particular water usage monitor 10 with a particular position in the water network 110.

The water usage monitors 10, utilizing the self-charging functionality of the power generator assemblies 34, can provide water flow information (e.g., flow rate, temperature, pressure, clarity, purity, etc.) in an on-demand and/or continual basis. The ability to monitor flow characteristics in specified regions of the water network 110 can enable precise and accurate identification of leaks, blockages, clogged/expired filters, mechanical failure, and/or other problems in the water network. For example, the overall arrangement of the water monitors 10 with respect to the pipes 112, 114 is known by the service provider who, in turn, can group the water monitors 10 in any number of groupings 120, 130, 140. If an abnormal flow rate were detected in a first group 120 of monitors, but flow rate appeared as expected in a second group of monitors 130, the technician or other service provider could quickly identify the portion of pipe or the particular monitor 10 having the problem or deficiency. In other words, the unique identification of the water monitors 10 with respect to their location in the water network 110 can facilitate expedient and accurate identification of defective pipes and monitors based upon the information contemporaneously gathered by the monitors 10 through the system 110 and groupings 120, 130, 140. Exemplary water networks 110 could include public utilities, agricultural arrays, golf courses, or other water networks.

Other applications of the disclosed live-monitoring network include analysis of water usage and other characteristics over a geographic region. The information collected from the individual monitors 10 distributed throughout a region could be compared and analyzed to determine such information such as climate change, degree of drought, flooding, and other information. For example, higher water usage in a specific grouping or distribution of monitors 10 can indicate a more severe drought, higher temperatures, and/or other environmental and usage characteristics. This data and analysis can be correlated to data received from other groupings of monitors in other locations, as well as to known environmental data such as temperature, humidity, sunlight, rainfall, and other data.

The live, geographically-correlated data from the monitors 10 could be used by utilities and other entities to identify excessive use of water by one user compared to other users. For example, the network of monitors 10 could identify that a specific user in a given region or industry uses considerably more water than other users in that same region or industry. The utility or other entity could modify its billing and/or distribution structure to discourage wasteful use of water with respect to the abusing user.

The information and data gathered from each monitor 10 can be stored in the cloud network 102 or elsewhere. The stored information can be correlated to a given monitor 10, given location, given user, given appliance (e.g., sprinkler, water fountain, etc.), and/or to some other unique identifier. The storage of such correlated data can facilitate faster and more accurate analysis of the live data provided by the monitors 10. For example, live monitor data indicative of leaks or blockages can be correlated to historic monitor data and/or data from monitors 10 in other locations to further confirm the accuracy of the live monitor data.

In some applications, the information and data gathered form the monitors 10 can facilitate optimization of a given application. For example, data gathered from monitors 10 in an irrigation system can indicate misdistribution of water in one or more zones of the irrigation system. Such misdistribution could, for example, indicate improper accounting for elevation changes, improper valve settings or pipe diameters, or improper sprinkler usage. Similar analysis could be performed on golf courses, municipalities, and other systems.

As illustrated in FIG. 14, a process of using the water usage monitors 10 can begin with the step of selecting the installation sites for the monitors. These sites can include water pipes or other water flow passages. For example, monitors 10 could be installed in commercial, residential, agricultural, utility, and/or other water systems. The process of use can continue with the step of installing the meters 10. The meters 10 can be installed in-line with a water flow passage, at the downstream end of a water flow passage, at a juncture of a plurality of flow passages, and/or at the upstream end of a water flow passage. Before or after installing a given meter, the step of syncing that meter with the network 90 can be performed. Syncing the meters 10 can include scanning a visual code (e.g., a barcode, QR code, alphanumeric code, color coding), an RF identifier, or some other unique identifier. In some applications, syncing the meters 10 includes manually entering an alphanumeric code. Once installed and synced, the monitors 10 can perform the step of collecting and transmitting raw data (e.g., voltages, temperatures, pressures, etc.) to the network hub(s) 100. The step of transmitting data from the network hub(s) 100 to the cloud 102 can be performed after or concurrently with the step of transmitting data from the monitors 10 to the network hub(s) 100. The system 90 can take the step of processing the raw data to calculate flow parameters such as flow velocity, pressure, and other flow features. In some applications, additional calculations can be performed to determine leaks, clogs, mechanical failures, and other problems or issues in the network 90 (e.g., in a flow meter 10 and/or in the water flow passages between flow meters 10). Based on the performed calculations, the system 90 or a system operator can request targeted maintenance or other service on the network 90. In some cases, the step of transmitting data or operational commands to the meters 10 from the cloud 102 is performed. In some applications, one or more of the steps of the process are performed in an order other than the order illustrated in FIG. 14.

FIG. 15 illustrates a process of using the network 90. To begin, a user or installer of the monitors can download a mobile application configured to facilitate installation of the monitors 10 and/or hub(s) 100. In some cases, the installer can use a hardware device pre-programmed with installation software. The installer can then install the monitors 10 and hubs 100 in the desired locations for monitoring. Prior to or after installation of the monitors 10 and hubs 100, the installer can scan or otherwise enter unique identification information from the monitors 10 and hubs 100. Such unique identification information can include a barcode, QR code, alphanumeric code, color coding, an RF ID, or some other unique identifier. The monitors 10 and hubs 100 can be configured automatically establish communication protocols between each other and the network of distributed servers 102. In some applications, the installer or user establishes such protocols. The communication protocols can establish a mesh network of monitors 10 and/or hub(s) 100.

The network 90 can be configured to monitor the voltage signals from the monitors 10 in real time and to transmit the monitor data to the cloud 102 via the one or more hub(s) 100. The monitor data (e.g., voltage from the turbines, pressure sensor data, temperature sensor data, and/or other sensor data) can be analyzed on the cloud 102. The data and/or analysis can be presented to the user. Such presentation can include alerts, warnings, requests for maintenance, and/or other reports. The cloud 102 can push software updates and/or other communications back to the monitors 10 and hubs 100 to facilitate efficient and reliable operation of the network 90.

FIGS. 16A-16F illustrate an additional embodiment of a water or fluid monitor 200 that incorporates a remotely controlled valve apparatus 202 that can be controlled by the system 90 to enable or disable fluid flow at particular regions of the fluid system such as a water system in the manner that will be described in greater detail below. As shown in FIG. 16A, the system includes a housing 130 with a fluid flow path 204 that has an inlet 206 and an outlet 210. Fluid flows down the flow path from the inlet 206 to the outlet 210 and passes through a power generator 212 in much of the same manner as described above. The flow path 204 and the power generator or turbine component 212 comprise a wet section of the housing 230. The housing also includes a dry section that houses electronics and the like as described above and as will be described in greater detail below. The inlet 206 and the outlet 208 are shown to be threaded to facilitate the installation of the monitor 200 on a water line in a water system or any other type of fluid line in a fluid sensor.

Further, as is shown in FIG. 16A, the pipe also includes a controllable valve 222. The controllable valve 222 is preferably solenoid activated and can be turned on and off in response to signals received from the network 90 via the cloud 120 and hub 100 (FIG. 12) in the manner described below. In one implementation, there is a diverter in the controllable valve 222 that diverts a portion of the fluid flow into a universal coupler 214.

The universal coupler 214 preferably is suited to receive on an end one of a number of different types of sensors 216. The universal coupler 214 can comprise a male or female type coupler based on deployment design. As shown in FIG. 16A and 16F, the universal coupler 214 is attached to a threaded outlet of the controllable valve 222 and has a generally L shaped appearance although different shapes of couplers can be used without departing from the scope of the present teachings. The universal coupler 214 has a threaded outer end 226 that can receive the sensor 216 such that water or fluid provided from the diverter in the controllable valve 222 can be delivered to the sensor 216.

The sensor 216 one of a number of different sensors such that the monitor 200 can be customized to sense one of a number of different parameters about the fluid that is flowing through the monitor. For example, the sensor 216 may comprise a pressure sensor or may also comprise a pH sensor that senses the pH of the fluid or it may be a sensor that is sensing another characteristic of the fluid such velocity, viscosity, purity, clarity, pressure, temperature as contamination sensors, element sensors and the like. It will be appreciated that any of a number of different types of sensors can be used in this system without departing from the spirit and scope of the present teachings. Additional sensors such as conductivity, salinity or turbidity in the water may also be used.

The universal coupler 214 can thus receive any of a number of different sensors and it can also be capped off if no additional sensor is being used. Thus, the universal coupler 214 permits great flexibility in configuring the monitor 200 for different applications.

As shown in FIGS. 16A and 16B, the components of the monitor 200 are housed in the housing 230 that is formed of two housing members 231 a and 231 b. The housing members 231 a and 231 b are secured together with screws 232 and forms a generally rectangular shape and one or more gaskets 233 may be interposed between the housing members 231 a, 231 b to form a watertight enclosure. On one side of the housing 230, there is an inlet opening 234 and on the other end an outlet opening 236 that allow the fluid flow path 204 to be connected to the fluid line that is being monitored (See, also FIGS. 16C and 16D).

As is shown in FIG. 16A and 16B, the flow path 204 is generally aligned along one side of the housing 230 and is positioned within a space defined by the first housing member 213 a and the coupler 214 extends towards the opposite side of the housing. As is shown in at least FIG. 16B, the coupler 214 also extends upwards such that the sensor 216 can be positioned within the space defined by the second housing member 231 b to make efficient use of the space within the housing 230 and reduce the overall footprint of the monitor 200.

The monitor 200 also includes communications and control components 240 that connect the monitor 200 to the cloud 102. The communications and control components 240 include control components that can initiate testing by the sensor 216 and can cause opening and closing of the control valve 202 via the solenoid 203. As discussed above, the monitor 200 may be partially or fully powered by the generator 212 and may also include battery backup power for additional or supplemental power. The power configuration, communications configuration and associated circuitry is substantially the same as in the embodiments described previously. The communications and control components may also include an antenna 242 that may permit wireless or RF communications with hubs 100 and the cloud to permit two-way communications between the monitor and the overall system. This enables the overall system to receive data from the monitor 200 and also allows the monitor's sensing and flow operations to be configured based upon the results of the received data. For example, as will be described in greater detail below, the flow data or the fluid pressure data may provide an indication of a leak somewhere in the system which can then be pin pointed and the relevant control valve 202 in the relevant monitor 200 can then be closed to stem the leak.

As shown in FIGS. 16A, E and F, the monitor 200 also includes the turbine component 212 which provides electrical power to the system and also provide flow data indicative of the level of water flow through the pipe 204. The turbine 212 includes a housing 250 that is generally circular in shape and is comprised of two housing members 251 a and 251 b that are screwed together with screws 252. The housing members 251 a, 251 b may also include a gasket interposed there between so as to secure the watertight integrity of the inner portions of the housing 230 that have the sensor, 216 and the communications and control components 240.

Inside of the housing 250 there is a turbine member 254 that is mounted on an axis 256 so as to rotate. The turbine member may comprise in one non-limiting embodiment, a Pelton turbine. The turbine member includes a plurality of curved vanes 260 where the curvature is oriented be concave in the direction of the inlet 206 of the monitor 200 so that the concave portion receive fluid from the flow path 204 via an inlet 262 of the turbine housing 250. As is shown in FIGS. 16B and 16F, the flow 204 includes a reduced diameter section 262 that is coupled to the turbine housing 250 such that the water is pressurized before it is injected into the turbine housing 250 and contacts the blades of the turbine member 254 to increase the force of the water on the turbine member 254.

The spinning of the turbine member 254 results in power that can be provided to the communications and control components 240 in substantially the same manner as described above and also results in flow information of the amount and volume of the water that is flowing through the monitor 200 being captured by the flow monitor 266 that can also be provided to the overall system for evaluation and capture in the manner that was described above. Advantageously, piezoelectric elements may also be included (not shown in drawings) that may generate additional electrical power due to vibrations caused by the water flow. As is shown in FIGS. 16A, E and F, the turbine housing 250 is positioned on one lateral approximately half side of the housing 230 and occupies substantially the entire width of the housing.

As shown in FIG. 16A and 16F, the system can also include a power outlet 280 such that power can be provided from remote sources when they are available. The monitor 200 is thus readily adaptable to different deployment scenarios ranging from scenarios where different things are being sensed to scenarios where the power has to be provided by the monitor itself.

As discussed above, this embodiment of the monitor 200 includes controllable components such as the controllable valve 202. The communications components 220 are configured to permit two way communications which allows for the control of each of the monitors 200 deployed in a particular system from the cloud via the network 100 and the hubs 10 as described above in FIGS. 12 and 13. In one particular advantageous implementation, the flow data of a plurality of different monitors 200 can be monitored to determine the location of a leak.

For example, if there are two successive monitors along a fluid flow path and the downstream monitor is detecting less fluid flow than an upstream monitor that is not explainable by other components in the path, one likely cause of the reduced fluid flow is the existence of a leak in this path. When this is detected, in addition to various notifications being provided in the manner described above, the cloud can also be used to send signals via the network 100 and the hubs 10 to the appropriate monitor 200 to have the valve 202 closed to thereby stop the flow of fluid along this path.

FIG. 17 is a flow chart that illustrates one embodiment of operation of a system of monitors, such as the monitor 200 that is installed on a variety of different fluid lines in a fluid system, such as a water system. The process of using the water usage monitors 10 can begin with the step of selecting the installation sites for the monitors. These sites can include water pipes or other water flow passages. For example, monitors 10 could be installed in commercial, residential, agricultural, utility, and/or other water or fluid systems. The process of use can continue with the step of installing the monitors 10. The monitors 10 can be installed in-line with a water flow passage, at the downstream end of a water flow passage, at a juncture of a plurality of flow passages, and/or at the upstream end of a water flow passage. Before or after installing a given monitor, the step of syncing that meter with the network 90 can be performed. Syncing the meters 10 can include scanning a visual code (e.g., a barcode, QR code, alphanumeric code, color coding), an RF identifier, or some other unique identifier. In some applications, syncing the monitors 10 includes manually entering an alphanumeric code. Once installed and synced, the monitors 10 can perform the step of collecting and transmitting raw data (e.g., voltages, temperatures, pressures, etc.) to the network hub(s) 100. The step of transmitting data from the network hub(s) 100 to the cloud 102 can be performed after or concurrently with the step of transmitting data from the monitors 10 to the network hub(s) 100.

The system 90 can take the step of processing the raw data to calculate flow parameters such as flow velocity, pressure, and other flow features. In some applications, additional calculations can be performed to determine leaks, clogs, other anomalies, mechanical failures, and other problems or issues in the network 90 (e.g., in a flow meter 10 and/or in the water flow passages between flow meters 10). Based on the performed calculations, the system 90 or a system operator can then decide if a leak is taking place. If a leak is not taking place, the system can continue collecting and monitoring the data that is being captured by the monitors. If, however, a leak is detected, by, for example, comparing flow rates of adjacent monitors and looking for anomalies, the leak can then be located. As an example, if there are two monitors on a single fluid line and the downstream monitor is detecting lower water flow, or pressure than the upstream monitor, then the leak can be determined to be on the line between the two monitors. Naturally, more sophisticated analysis can also be performed on the data that is being captured to detect and localize leaks.

Once the leak has been located, using the monitors 200 described above in connection with FIG. 16, the system can transmit a close valve signal to the appropriate hub which is then transferred to the microprocessor of the appropriate monitor 200 which then closes the valve 202 and isolates the leak. At the same time, signals can be sent to the system operator of the detection of the leak and the shutdown signal. Alternatively, permission from the system operator to shut down the leak may be sought ahead of time but the leak can be the shut down as needed.

Having the controllable valves 202 in the monitors permits the system operator to not only shut down leaking pipes but it also affords the system operator to use the cloud system to configure the water system as needed. As another example, in an irrigation system, the system operator can remotely open and close valves as needed to achieve irrigation in different areas.

The monitor 200 paired with the system 90 that includes the hubs 100 and the network 100 provides an automated, unmanned and remote solution to water or fluid flow issues. The characteristics of the system allow for fluids, such as water to have parameters sensed in-line, then monitored and evaluated on line which allows for real time but remote and automated analysis of the fluid or water system.

While the preferred embodiments of the present disclosure have been described above, it should be understood that they have been presented by way of example only, and not of limitation. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the disclosure.
